FYI, been playing a stealthy illusionist/thief which is pretty new for me, usually I have a much more direct approach. However, this PC is pretty squishy (Master difficulty, AC around 308, health 300ish, no enchanting, no smithing, alchemy is strong) so there's lots of sneaking, backstabbing, laying poison runes, and running away. It's a little slow, but it gets the job done, right?

So finally got illusion skill to 100 at level 54 and completed the ritual spell from Drevis. Thought I'd try the Mayhem spell and headed over to Karthspire (loads of forsworn and a hagraven). Man, they didn't have a chance! Around three blasts and everyone was gone except one sentinel. Amazing! Destruction magic? Forget about it. This Mayhem spell just cleared the entire area in minutes.

Decided to ratchet things up and headed over to Liar's Retreat (a very, very, hairy fight with a mix of eight or nine Falmer Sulkers, Gloomlurkers, and Shadowmasters in an enclosed space) which is always a litmus test, in my opinion, of a PC's toughness. Hit them with Mayhem three times and got most of them but a few proved immune (need better fortify illusion potions).

All together, this is an incredible spell. You can clear an entire area (if not an entire, small dungeon) in complete safety. Kinda puts the other schools' Master spells to shame.

Onto Broken Oar grotto, maybe Hag's End as well. Look out baddies of Skyrim...

I have used the scroll of mayhem. Love it against

Illusion's a beautiful thing isnt it?

Good. Now, combine Illusion with Destruction. Calm them first, then blast them

I don't know what to make of Destruction anymore. I mean, here's a Master-level illusion spell clearing out entire sites and I've got no fortify gear (none) and only 350ish Magicka. I've got some good perks for cost reduction and recovery, but those don't feel like exploits. Plus, I'm playing at the game's Master difficulty.

I'm now really tempted to try the CW quest line (which I've already done but don't find particularly interesting) just to see the Call-to-Arms spell in action during the fort battles.

Master Illusion + Master Conjuration = sic sic combination.

i love illusion for its calm spells but when it comes to bandits killing eachother there isnt something better to see!

Illusion always been the most powerful spell set in TES series.

Back in Morrowind and Oblivion, I actually made the right spells that can make anything attack anything else! It was awesome! The Mayhem spell can't even compare since it is limited to I think level 37 at max.
